Description: Great quality test roller weights for Honda DIO/Elite, GET, and 139QMB 4-stroke engines. Lower your stock weight (8gm) with 6s or 7s for a great performance upgrade for better take and just plain replacing worn out stock weights. 16X13 mm roller set for 139QMB and many other scooters. Play with some different weights and make it rip! Includes 36 Roller Weights, from 3gto 14g. Lighter roller weights will increase RPM for any given road speed. Heavier weights will lower RPM for any given road speed. Must be put in a 120° pattern!
For those of you unfamiliar with roller weights, they are an important tuning device and have a significant impact on your scooter's performance! They should be checked/changed every 1000 miles (per maintenance schedule) to keep your scooter running tops. Over time, roller weights will develop flat spots which will impair the performance of your scooter. A good indication that your rollers are worn is increasingly high revs for a given speed and/or decreased top speed. Replacing worn rollers will restore and actually improve your low-end power and especially your top speed. Fuel efficiency will also improve dramatically!
Compatible with most variator roller's housing on the market works on Yamaha JOG Minarelli engines, Chinese Yamaha Clones such as the 1PE40QMB 1E40QMB engines, Honda Ruckus, 139QMB 50cc 4 stroke engines, Vertical Honda DIO style 2 stroke engines found in SYM and Kymco Scooters, as well as Aprilia Scooters with Piaggio engines, and Franco-Morini 50cc engines found in the 1E41QMB Suzuki AD50 AG50, TGB R50X, TGB 101, TGB 303 and Peirspeed Scooters.
Installation: Make sure variator drive face is seated properly and not get its teeth chewed by the Bendix: 1. Slack the belt by opening the CVT clutch gives belt slack to the variator side. 2. Then install the variator drive face while lifting the slack belt further away from the center boss if done properly should not see any splines between variator drive face slop-side and boss flat-side. Should be flushed together. 3. Then install existing variator fan, washer, and hand-tight nut. 4. Finally, apply blue Loctite, torque nut to 30-35ft lbs. For reassurance please consult your manufacturer variator torque specs.
